Furnace Installation - Wiring

Wiring

Before beginning any wiring, study the appropriate wiring diagram for your unit. Also refer back to figures C or D for an example of what the completed job will look like. It is your reponsibility to follow all state and local electrical codes. Locate the best place to route the power for the blower, and drill a 7/8” hole in the filter box. This hole size will accomodate a “romex” connector. Attach the blower and power wires as shown on the appropriate wiring diagram.

Once you have the plenum installed, the fan control with high limit switch can be installed. The Fan control/ high limit switch is packaged with a jumper between the two sets of terminals inside. REMOVE THE JUMPER WIRE INSIDE THE FAN CONTROL. The fan control should be installed in the right side of the plenum and 12 to 18 inches above the top of the furnace. A separate conduit should be run from the fan control to the junction box.

Mount the thermostat in a central location of the area you want to heat. Run two wires to the junction box, from the heating terminals on the thermostat. 22 gauge or thicker wire is acceptable.

The next step is to run a 120 volt line from your breaker panel to the junction box. Attach all wires according to the corresponding wiring diagram, and install the relay into the junction box. DO NOT TURN ON THE BREAKER UNTIL ALL WIRING IS COMPLETE AND THE RELAY IS SECURED.
